+In this exercise, you have to rewrite FeedbackControlComponent. It should implement Control Value Accessor interface.
+This interface is crucial for creating custom form controls that can interact seamlessly with Angular's forms API.
+The primary goal is to use control in the feedbackForm to eliminate the need for using @Output to retrieve the value and check it.
